The introduction of a simplified model for Non-linear behavior of the structure foundation for seismic rehabilitation

During the applying the seismic force on the building's structure , buildings foundation and soil structure has an important role to depreciating of force and finally unsuitable performance of these elements ,cause the irreparable damages and instability of challenges of buildings .According to the researches , which have done on more than 05 retrofitting buildings , some tables had obtained which help us to evaluate the structural foundation quickly and in compared to linear and nonlinear Analysis is more detailed .using these evaluating tables lead us to recognize rather correct level of performance of structure foundation , and finally reliable results are obtained from primary and secondary behavior of the structure
